The increasing number of drones brings various issues like security risks, increasing air traffic, misuse or crash of drones, and so on. Blockchain can provide the solution to mitigate these problems of drones. Hence, in this article, we have presented the Blockchain of Drones (BCoD), a conceptual approach of collaboration between blockchain and IoD to make drones advantageous through blockchain properties. But the main challenge for adopting blockchain is scalability as consensus in blockchain relies on the message communications by replicated nodes to attain flexibility against faulty nodes. Considering this, we present an advanced byzantine fault tolerance (ABFT) consensus for drone‐based applications. This protocol provides scalability with minimum cost and resources for achieving general agreement. It uses only f + 1 resources in normal case and 2f + 1 resources in faulty case with O(n) communication complexity. The systematic analysis and evaluation show that the ABFT improves the performance of the system for a wide range of networks compared with existing BFT systems.

无人机服务具有拜占庭容错共识的区块链机制

无人机数量的增加带来了各种问题，例如安全风险，空中交通的增加，无人机的误用或坠毁等。区块链可以提供缓解无人机这些问题的解决方案。因此，在本文中，我们介绍了无人机区块链（BCoD），这是一种区块链与IoD之间协作的概念方法，旨在通过区块链属性使无人机更具优势。但是采用区块链的主要挑战是可伸缩性，因为区块链中的共识依赖于复制节点的消息通信来获得针对故障节点的灵活性。考虑到这一点，我们提出了针对基于无人机的应用程序的高级拜占庭容错（ABFT）共识。该协议以最小的成本和资源提供了可扩展性，以实现总体协议。它只使用f + 1个资源在正常情况下和2 ˚F + 1个中有故障的情况下，资源与ø（Ñ）通信的复杂性。系统分析和评估表明，与现有的BFT系统相比，ABFT可以提高系统在各种网络中的性能。
